1/12 INFRACTION GROM 3S 4X4 RTR Brushless All-Road Street Bash (Battery & Charger Included), Yellow/Black
ARRMA INFRACTION GROM 3S BLX 4X4 RTR Overview
Big INFRACTION energy, scaled down and ready to run wild anywhere pavement can take you.
The ARRMA® INFRACTION™ GROM 3S BLX 4X4 RTR is the first-ever ARRMA all-road street basher on the GROM platform. It’s a category-defining 1/12 scale machine that packs the tire-roasting, drift-happy chaos of the full-size INFRACTION into a compact, affordable package. Whether you’re graduating from your first RC or you’re an INFRACTION diehard looking to add a small-scale bash buddy to the fleet, the INFRACTION GROM 3S removes the barriers and hands you the keys to real street domination.
PowerGuard, ARRMA’s smart speed-management system was first introduced on the MINI KRATON and is now built into the INFRACTION GROM 3S from the ground up. Right out of the box, Adrenaline Mode delivers a confident 30+ MPH on the included 3S battery, no extra purchases required. It’s great for beginners wanting to get started with the INFRACTION GROM. When you’re ready for more, insert the included PowerKey and unlock full Chaos Mode: real, verified 50+ MPH insanity that turns any parking lot, driveway, or dirt pile into your own personal thunder dome. Two ways to bash. One way to dominate.
All that speed stays manageable thanks to Spektrum™ Dynamic Stability Control (DSC). With four selectable modes, off for zero correction and total manual control up to high for maximum safety and beginner-friendly confidence, DSC automatically applies steering correction so every slide stays controllable, not chaotic. Dial it back as your skills grow, or leave it engaged and just enjoy the ride.
Underneath, the INFRACTION GROM 3S is built ARRMA tough. A sealed center differential with metal spur gear, easy-access front and rear differentials, and an enclosed 4X4 drivetrain keep dirt out and durability in, while front and rear bumpers with a body location system and a street-tough composite chassis shrug off curb hits without blinking. Double wishbone, four-wheel independent suspension and oil-filled shocks keep the low-slung chassis planted through every corner, and aluminum 12mm wheel hexes are built to withstand hard launch abuse, run after run.
High-performance dBoots Hoons white compound belted tires come standard for grip that owns the pavement, wrapped around a quick-release, clipless body design that means fast battery swaps and easy chassis access between runs. Additionally, SmartFit’s click-out battery system means no straps and no hassle, just a precise, super-secure fit every time you power up.
The ARRMA INFRACTION GROM 3S BLX 4X4 RTR delivers. Because the streets just became your bash zone.
